description="
A library that provides functions for manipulating Unicode strings.

Text files are nowadays usually encoded in Unicode, and may consist of
very different scripts from Latin letters to Chinese Hanzi, with many
kinds of special characters accents, right-to-left writing marks,
hyphens, Roman numbers, and much more.  But the POSIX platform APIs for
text do not contain adequate functions for dealing with particular
properties of many Unicode characters.  In fact, the POSIX APIs for
text have several assumptions at their base which don't hold for
Unicode text.

This library provides functions for manipulating Unicode strings and
for manipulating C strings according to the Unicode standard.
